Chlorhexidine vs povidone‐iodine: Reduction in level of contamination by particles >5 um (droplets) at <2 m from patient's oral cavity
- Population
- Dental patients undergoing aerosol-generating procedures (AGPs) and the dental healthcare providers treating them
- Intervention
- Chlorhexidine
- Comparison
- povidone‐iodine
- Outcome
- Reduction in level of contamination by particles >5 um (droplets) at <2 m from patient's oral cavity
It is very uncertain whether chlorhexidine (CHX) changes reduction in level of contamination by particles >5 um (droplets) at… compared with povidone iodine (very low certainty).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
